Tilaka

In Hinduism, the tilaka, colloquially known as a tika, is a mark, most often applied to the forehead at the point of the ajna chakra (third eye or spiritual eye), though it may also appear on other parts of the body such as the neck, hand, chest, or the arm. The tilaka may be applied daily for decorative purposes, as a symbol of religious affiliation, for rites of passage, or other special spiritual and religious occasions, dependent on regional custom. It is also used to honour and welcome someone upon arrival.

Tilakas vary widely in shape and are made from various substances, including "ash from sacrificial fire or cow dung, sandalwood paste, turmeric, clay, charcoal or red lead."
